A bit much. Over the top. Where Gnarly or Brutal individually indicates something good, the combination of the two signifies a rape of both words.

1.) Something disgusting to the point of revulsion. Where if it were kicked a couple notches back it might be cool in the horror movie kind of way. But instead it's morphed into something grotesquely macabre.

2.) Incomprehensibly Impossible. A Jaw dropping event leaving the onlooker stunned. In a bad way. Such as someone who spends SO much of their lives playing video games, they're good to the point where it's sad.

1.) Dude, that song was pretty sick. It's way heavy... but that breakdown where they overlapped the sound clip of that chick getting raped and killed... brugnar.
